Patented Aug. 18, 1908.

Application filed August 26, 1907. Serial No. 390,106.

To all whom 'it may concern:

Be it known that I, FRED J. MOSER, acitizen of the 'United States, residing at Kane, in y the county of McKean and State of Pennsylvania, have invented new and useful Improvements in Bailers, of which the following is'a specication.

This invention relates to bailers and conslsts 1n certain improvements 1n the construction thereof as will be hereinafter fully dee scribed and pointed out in the claims.

One of the objects of the invention is the improvement of the bailer tube itself.

Another obj ect is providing means whereby the bailer tube may be filled regardless of the depth of mud in the well.

Other objects of the invention will appear from the specification andclaims.

The invention is illustrated -in the accompanyi-ngdrawings as j follows Figure 1 is a central longitudinal section of the device on the line 1-1 in Fig. 3. Fig.` 2

is a section on the line 2-2 in Fig. 1. Fig. 3 1s a side elevation of the lower end of the baller tube.V Fig. 4 is a section similar to that of Fig. 1 with the parts in a different position.

1 marks the bailer tube, cap 2 is secured to the tube 1 by means of a collar 3. The pin4 extends through the o ening 5 in the cap 2 and is provided with a ead 6, and the'screw threaded end 7 to which a cable or other means for raising or lowering the bailer may.

be attached. These are of ordinary construction. y

The lower end of the bailer is formed of a ta ered tube 8, which is connected to the tube 1 by a collar 9. `The tapered tube has Va discharge opening 10 at the side and a tapered sleeve 1 1 is arranged on the tube 8 and has an opening 12 that maybe brought into register with theppening 1() to discharge the bailer.

By making the lower part 8 of theV tube tapered and the closure sleevevll similarly tapered a .tightl fit maybe maintained, the taper taking up the wear. The sleeve 11 is preferably free to move downwardly on the tube under the influence of gravity to maintain a close ii't. -The collar 9 forms a shoulder 14 which revents the sleeve from sliding up .on the tu e 1.

The diaphragm 15 at the lower end of the vtube has a passage 16 through it which is controlled by the clapper valve 17 i I prefer to make the diaphragm 15 approximately on a level with the opening 10 so that the mud is completely discharged from the tube 1 with eachoperation; This prevents the clogging of the valve.

To facilitate the mounting of the valve 17,

-I indent the walls of the side 8, at 18 forming a socket 19, the shank 20 of the valve eX- tending into this socket is secured by the pivot pin 21. By indenting the walls of the tube, both the guide socket 19 is formed and a place for the heads of the pivot pin is pro# vided so that the valve may be easily and securely mounted.

In the operation of bailers, as ordinarily constructed, the mud would be delivered directly from the well to the bailer tube through the clapper valve. In deep wells ,the small amount which can be raised with each operation makes the cleaning of a well a rather tedious matter. This is true even though a high level of mud is in the well. It is evident that as the level of mud recedes the load that can be vlifted with an ordinary bailer diminishes. I have provided a means for obviating this difficulty which consists in providinga pump by means of which the mud is forced into the bailer and the bailer completely filled regardless of the level of mud in the wel-l.

The tube 22 is screwed into the bottom of the 4end 8; it telescopes a tube 23 which forms the working barrel of a pump. A collar 24 is arranged on the end of tube 22 and 27 at the end of the tube 23 so that the.

pump including thebarrel 23 is lifted with the plunger tube 22, the plunger tube 22 having a limited telescopic movement relatively to the tube 23.

I prefer to make the end 28 of the collar 26 cone shape. The purpose of this is to force the packing 25 into engagement with the walls of the working barrel 23 as the plunger tube 22 is forced downward by the l,Wei ht of the bailer above so that the mud in t e working barrel is forced through the tube 22 past the clapper valve 17 into lthe .bailer l1. It is evident that the heaviest work of the plunger is in this forcing action so that a tighter joint is assured during the forcingstroke to the pump. It also takes up the wear in the packing so that a joint is effected even though the packing is much worn. The strainer 29 extends from the workingA barrel, being preferably formed of the same tube, and the diaphragm 31 is secured within the tube by means of collars 30 riveted to the tube. The diaphragm has the passage 32 through which the mud enters the working barrel. This passagev is controlled by the check valve 33 which operates in the manner common to a working barrel in a pump. The bailer having been filled, it is drawn up and with the initial upward movement the plunger tube is drawn up in the working barrel, thus taking in a fresh charge of mud. This mud is objectionable, in that from its nature it is a t to pack in the working barrel during t e time the bailer is being raised 4and lowered so as to seriously interfere with the working of the device. To obviate this I attach a slotted link to the valve 33, and extend a pin 35 through the slot in the link 34. This pin is secured to the tube 22. With the normal operation of the pump the slotted link is of sufiicient length to permit the valve to operate in its normal manner but as the pump is raised carrying the plunger to its extreme position the pin 35 acts on the link 34 to lift the valve 33, as shown in Fi 1, thus permitting the mud in the Woring barrel to escape.

The operation of the bailer is as follows: The apparatus is lowered into the well by means of the connection 7, the strainer 29 being preferably at the bottom of the Well. The connection 7 is then reciprocated carrying with it the bailer 2, and operating the tube 22'in the working barrel23. The tube 22 operates and acts as a plunger. On the `upward stroke mud and water is drawn into the working barrel, past the valve 33. On the downward stroke, the valve 33 is closed in a manner common to the lower valves in pumps and the charge is forced through the valve 17. The reciprocation of the plunger is continued until the bailer is filled. The apparatus is then raised to the top of the well. The sleeve 1l is so turned as to uncover the discharge opening 10, so that the bailer tube may empty. As before stated the mud in the working barrel 23 is discharged with its initial upward movement by reason of the fact, that valve 33 is opened by the action of the link 34 and pin 35.
